中尺度模式下海上风电场布局方式对运行特性的影响
The impact of offshore wind farm layout on operational characteristics in mesoscale modeling
【摘要】 为了探究真实大气环境中布局方式对海上风电场尾流效应和功率输出特性的影响,基于中尺度天气预报模式(WRF)耦合风电场参数化模型,以北海海域某3.6 MW机组构成的8×8理想风电场为研究对象展开模拟,量化分析了不同布局方式下海上风电场尾流效应和功率输出特性.研究发现:在真实大气环境中,增大风电场内风力机轴向间距和展向间距,风电场尾流长度可以缩短1.70~7.21 km,最大风速亏损降低0.6~1.1 m/s,功率输出提升5.3%~21.8%;在众多布局方式中,错列布局对整场功率提升最明显,可达23.8%;但是风力机轴向和展向间距的增大会导致风场整场效率下降15.1%~32.3%,风电场规划设计时须结合其他因素合理规划与考虑.
【Abstract】 In order to explore the influence of layout configurations on wake effect and power output characteristics of offshore wind farms in real atmospheric environment,based on the mesoscale weather research and forecasting(WRF) model coupled with wind farm parameterization model,a wind farm consisting of 3.6 MW wind turbines in the North Sea was taken as the study object.Different layout configurations were quantitatively analyzed to assess wake effects and power output characteristics of offshore wind farms.It is found that in a real atmospheric environment,increasing the axial and spanwise spacing of wind turbines in a wind farm can shorten the wake length of the wind farm by 1.70~7.21 km,reduce the maximum wind speed loss by 0.6~1.1 m/s,and increase power output by 5.3% ~21.8%. Among various layout methods,the staggered layout has the most significant increase in overall power,reaching 23.8%. However,increasing axial and radial spacings led to a decline in overall wind farm efficiency by 15.1%~32.3%.Therefore,reasonable planning and consideration should be combined with other factors in wind farm planning and design.
